New films in Columbia theaters this weekend.

“21 and Over” (R) A med school hopeful celebrates his milestone birthday with friends on the eve of his entrance interview. If you’re into on-screen debauchery, you should be in good hands — the film was co-directed by the writers of “The Hangover.” Forum: 12:15, 2:30, 4:50, 7:35, 9:50 p.m.; midnight tomorrow and Saturday. Stadium: 2:20, 4:40, 7:30, 10:10 p.m.

“David Holzman’s Diary” (unrated) Screening as part of the “Neither/Nor” series, a joint effort of Ragtag Cinema and the True/False Film Fest, this 1967 film documents the ramblings of a troubled young man. It looks like a documentary but is a work of fiction and, according to the Ragtag website, “anticipates (and pre-satirizes) the next half-century of first-person cinema.” Ragtag: tomorrow 7:30 p.m., Saturday 8 p.m.
